This changes the behaviour of _dbus_logv() if _dbus_init_system_log() was not called. Previously, _dbus_logv() would always log to syslog; additionally, it would log to stderr, unless the process is dbus-daemon and it was started by systemd. Now, it will log to stderr only, unless _dbus_init_system_log() was called first. This is the desired behaviour because when we hook up _dbus_warn_check_failed() to _dbus_logv() in the next commit, we don't want typical users of libdbus to start logging their check failures to syslog - we only want the dbus-daemon to do that. In practice this is not usually a behaviour change, because there was only one situation in which we called _dbus_logv() without first calling _dbus_init_system_log(), namely an error while parsing configuration files. Initialize the system log "just in time" in that situation to preserve existing behaviour. Signed-off-by: Simon McVittie <smcv@debian.org>
